Can anybody help me get the associated Ac Delco Parts reference # for a distributor cap, rotor, spark plug wires, plugs ? There is a person in my area selling a bunch of OEM Ac Delco parts and want to know if it will fit my 1991 Pontiac Trans Am with the 5.7 liter engine. I went to acdelco web site and typed in the numbers but it doesn't mention anything for 1991 year. It says they match for the 1990 and 1992 Trans am with 5.7 liter engine. just want to be sure before I buy.

Thanks
